IMPROVEMENT IN BASE-BURNING STOVES.

To all whom it may concern:

Be it known that I, GEORGE G. HUNT, of the city of Chicago, in thecounty of Cook and State of Illinois, have invented certain Improvementsin Base-Burning Stoves, of which the following is a specification:

The nature and object of this invention relate to improvements wherebycertain parts which have heretofore been liable to be burned out anddestroyed areby this invention rendered far more durable.

Figure 1 is a combined drawing representing a vertical section on y y,Fig. 2, on one side of the center line, and on the opposite side of thecenter line an elevation of the stove. Fig. 2 is a top view of thefire-pot, showing clearly the des-cending-iiues G2.

In Fig. l, A is the base of the stove; B, the ash-pit;` C, a base-iiue;I), a horizontal plate forming the top of the flue C. C2 is a flue-stripseparating the iiue C from the ash-pit. E is a casing forming the upperpart of said ash-pit. F is the exterior wall of the flue C. G is one ofa series of lines. H is a ring holding the casing E in place.I I is thelire-pot. J is a curved annular plate resting by its outer edge on thetop of the wall of the lire-pot I., K is an annular open-work curvedplate resting on the plate J and surrounding the magazine L. L is amagazine for holding coal. M is the top plate of the magazine. N is thecover thereof. O is one of a series of upward and inward projections ofthe wall of the fire-pot, said projections forming an external cavity,O2, in the wall of said fire-pot. When the pipes G are in place there isthen formed an air-space or concentrating passage,

' O2, between the upper part of said pipes and the walls of the cavitiesO2 into which air oni below has a ready access, and, circulating aroundthe upper part of the pipes G, absorbs and carries off the heat from thewalls of the cavities O2, thus preventing them from being destroyed bythe heat. P is a curved annular plate resting by its outer edge on aiiange formed on the inner edge of the plate J. The plate P curves andprojects downward into the lire-pot I. From thence said plate P curvesupward and forms the lower part of the magazine; or it may be continuedupward to any desired height, and thus form the magazine itself. It isobvious also that the outer edge of the plate P, where it meets theplate J, may be extended in the line of said plate J so as to form thatplate also, if desired. the plate P is such th at it forms a diaphragmseparating the lower part of the magazine I from the combustion-chamberJ2, while, from its peculiar curved shape, the whole of the outer sideis exposed to the air, thus radiating a greater amount of heat into theroom, while at the same time the plate or diaphragm itself is rendereddurable. The outer side of the plate P conforms nearly to the inner sidethereof, thus forming a groove or U-shaped cavity7 Q, into and out ofwhich air may readily circulate through thel openwork plate K 5 or thisplate K may be dispensed with and a projecting flange from the magazineL may be placed at a short distance above the cavity Q for the purposeAof a shield to prevent coal and other substances from falling into saidcavity. This is, however, the object of the plate K. The smoke-pipe isin the rear of the stove,

but its position is shown at S, Fig. 2. The products of combustion passfrom the chambers J2 downward through the ues G into the base-flue C,thence back to the ascending-flue S, and off by the smoke-pipe.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The plate P, when made substantially in the manner and for the purposeshereinbefore specilied.
